SIP SIMPLE client ----------------- Copyright (c) 2008-2009 AG Projects http://ag-projects.com Description ----------- SIP SIMPLE client is a Python software library that allows for easy development of Internet communications end-points based on SIP and related protocols for voice, rich presence, session based instant messaging (IM), file transfers and desktop sharing. Other media types can be easily added by using an extensible high-level API. Background ---------- SIP stands for 'Sessions Initiation Protocol', an IETF standard described by RFC3261. SIP is an application-layer control protocol that can establish, modify and terminate multimedia sessions such as Internet telephony calls (VoIP). Media can be added to (and removed from) an existing session. SIP allows the endpoints to negotiate and combine any type of session they mutually understand like video, instant messaging (IM), file transfer, desktop sharing and provides a generic event notification system with real-time publications and subscriptions about state changes that can be used for asynchronous services like presence, message waiting indicator and busy line appearance. Features -------- The software allows you to create elegant real-time communications applications without having to read the +1200 RFC documents behind it. As a library with a high-level API, the toolkit can be used to add voice, instant messaging (IM) and rich presence functionality to any device as long as the Python/C environment is supported by such platform. Additional to the SIP standards implemented by the underlying PJSIP library and exposes through a Python API, this project implements session based instant messaging (IM), file transfer and multi-party chat sessions using MSRP protocol and its relay extension, publication and subscription for rich presence information such as availability, moods, activities and geo-location, management for presence rules, resource lists, RLS services documents using XCAP protocol. * Rich presence data model RFC3856, RFC3863 , RFC4479, RFC4481, RFC4482, RFC5196 * Presence watcher-info event package RFC3857, RFC3858 * XCAP protocol RFC4825 * XCAP presence rules RFC5025 * XCAP resource-lists and RLS-services RFC4826 * XCAP PIDF manipulation RFC4827 * XCAP-diff event package draft-ietf-simple-xcap-diff-09 * MSRP conference event package RFC4575 * MSRP protocol RFC4975 * MSRP protocol relay extension RFC4976 * MSRP ad-hoc multi-party chat sessions draft-ietf-simple-chat-03 * MSRP file transfer RFC 5547 * Desktop sharing draft-garcia-mmusic-sdp-collaboration-00 * Message summary event package RFC3842 * Bonjour multicast DNS draft-lee-sip-dns-sd-uri-03 Documentation ------------- For download and installation instructions, API description and other documentation see the files under docs/ directory.
